Flow Meter Parts Overview: Exploded Views of Transmitters, Liners, Sensors, and Coils
Quick Answer: Silver Automation Instruments supplies replacement and OEM flow meter parts with clear exploded views. You get transmitter modules, PTFE or rubber liners, measuring sensors, and excitation coils for DN10 to DN3000 electromagnetic flow meters. Send your pipe size, fluid type, temperature, and liner material to get a quote.
Exploded Views Help You Identify the Right Part
Exploded views break down a flow meter into individual components. A maintenance engineer can see the transmitter housing, liner, electrode sensor, coil assembly, and grounding ring. This removes guesswork during shutdowns. We have seen many sites in Southeast Asia hold a failed part in hand without knowing the exact model. The exploded drawing solves this.
We keep drawings for our SIS series electromagnetic flow meters. Each drawing shows the part number, material code, and assembly order. For OEM replacements, send us the tag plate photo. If the tag is gone, the process data usually gives enough clues.
Transmitter Parts and Common Failure Points
The transmitter converts the electrode signal into a flow reading. Typical output options include 4-20 mA HART, pulse, and RS485 Modbus. Many users replace only the transmitter when the display fails or the output drifts. In practice, the coil drive circuit and the analog input stage fail first. We stock remote and compact transmitters with IP67 and IP68 housings. For hazardous areas, order the ATEX Zone 1 version.
Liners Material Selection by Process Fluid
The liner is the wetted surface that protects the flow tube. PTFE works for acids and caustics. Hard rubber handles water and wastewater. Soft rubber suits slurries with large particles. PFA is common for food grade lines. A wrong liner material causes early failure. A customer in Vietnam replaced three rubber liners in one year because the water contained abrasive sand. We switched the liner to polyurethane and the meter ran without loss for two years.
Sensors and Electrodes in Electromagnetic Flow Meters
Sensors pick up the voltage generated by the conductive liquid. Electrode materials include 316L stainless steel, Hastelloy C, tantalum, and titanium. The sensor assembly also includes the electrode shield and signal cable. Do not mix electrode types with liner materials. For seawater and brine, choose titanium electrodes and PTFE liner. For high temperature chemical dosing above 120 °C, PFA liner with Hastelloy C electrodes gives stable readings.
Excitation Coils and Magnetic Circuit Behavior
Excitation coils create the magnetic field across the flow tube. The field strength affects signal stability. Most modern meters use pulsed DC excitation. That method saves power and rejects electrochemical noise. Coils are not often replaced unless the insulation breaks down or a customer washes the meter with high pressu
Exploded View Example DN100 Remote Electromagnetic Flow Meter
For a DN100 remote magmeter the exploded view includes the junction box, transmitter base, coil housing, PTFE liner, measuring tube, two electrodes, grounding rings, and four bolts. The sensor seats inside the liner pocket. The coils wrap around the tube outside the liner. This arrangement leaves no moving parts in the flow stream.
Recommended Parts and Model Matching
For clean water and wastewater choose the SIS-MAG-100 series with hard rubber liner and 316L electrodes. For acids and caustics choose SIS-MAG-200 with PTFE liner and Hastelloy C electrodes. For seawater desalination choose SIS-MAG-300 with PTFE liner and titanium electrodes. For food grade lines choose SIS-MAG-400 with PFA liner and 316L electrodes. All transmitters support 4-20 mA HART output.
How to Order Flow Meter Parts
You do not need to send the whole meter back. Send us the tag plate photo, the failed part name, your fluid, pipe size, pressure, temperature, and liner material. We match the part from the exploded drawing and quote the replacement. We ship parts to Southeast Asia, Oceania, Latin America, the Middle East, and Africa from our Nanjing warehouse.

FAQ Flow Meter Parts and Exploded Views
Can I replace only the transmitter on an existing electromagnetic flow meter?
Yes. Most transmitter failures do not require a new sensor. You can keep the old liner and coils. Send the sensor constant and electrode type for calibration.
How do I know which liner material my process needs?
Match the liner to the chemical compatibility chart. For acids use PTFE or PFA. For abrasive slurries use polyurethane or soft rubber. Share your fluid composition and concentration.
Do exploded views come with every replacement part order?
We send a drawing or a photo mark up with each quote. That way your maintenance team knows the exact assembly sequence and torque values.
What is the typical lead time for liners and transmitters?
Common parts in stock ship within 3 to 5 working days. Custom electrode materials like tantalum may take 2 to 3 weeks. Confirm at order time.
Can you supply parts for other brands?
Yes. We match parts by measuring the tube, liner thickness, coil resistance, and sensor constant. Send clear photos of the existing tag plate and any available drawings.
Need a specific flow meter part? Send us your fluid type, pipe size (DN), operating temperature in °C, pressure in bar, and liner material. A product engineer will reply with a quote and an exploded view for your assembly.
